noUsII-MOLDING MACHINE.

Application filed June 14, 1921. y Serial No. 477,363.

T 0 all whom t may concern:

Be it known that I, FRANK X. LAUTERBUR, a citizen of the United States,and a resident of Sidney, in the county of Shelby and State of Ohio,have inventedcertain new and useful Improvements in `Dough- MoldingMachines, of which the following is a full, clear, and exactdescriptionfreference being had to the accompanying drawings, formingpart of this specification.

My invention relates to dough molding machines and more particularly toattachments therefor which form extensions-of the lmeading elements ofsuch machines.

1n my Patent No. 1,167,187, dated January 4, 1916, I describe a 'form ofdough mold-` quickly and positively attached to a kneadmg box in suchmachines as in said patent and application for patent, wherebyadditional kneading may be imparted to the roll or coil of dough, saidunit to be driven by the power means for the machine to which it isattached.

Another object of my invention is to provide this extension unit withmeans for varying the shape of a roll of dough by making its endssmaller or larger than its central portions.

i Another object is to provide for driving mechanism for the extension,which can be adjusted to mesh with the conveyor belt drive of the mainmachine, no matter what adjustment is made in the said belt drive.

These objects and other advantages to be noted I accomplish by thatcertain construction and arrangement of parts to be hereinafter morespecifically pointed out and claimed.

In the drawings,

Figure 1 is a longitudinal section of the device partly in elevation.

Figure 2 is a sect-ion on the line 2--2 of Figure 1. i i

Figure 4 is another like Aviewf showing a third board. j,

Figure 5 is a side elevation showingthe unit in attachment to theVbuilt-in kneading lunit of one lof my machines. Y y l I have indicatedatl theside standards of the extension unit kneading device, same havinglower side crosspieces 2, a front cross piece 3, and-.a rear cross piece4, and bed forming top pieces 5.-4

`Set on the 'top'bars or bed are apair or more of arched straps 6, whichare held in place by means of bolts 7, so that they straddle themachine. These straps have central journal sleeves 9 having bosses 8,which suitable 'heads 10.

The sleeves areinternally'threaded to receive the screw posts 11,which'support` the" pressure board and are non-rotatably secured to saidboard, whereby the revolution` position of adjustment ofthe pressure" ofthe' sleeves will feed thescrews. along, and n adjust the position ofthe board. 4 v The sleeves have collars 12thereon,an'd

also sprockets 13, said'sprockets being con-` nected by a chain, wherebythe sleeves are held against reciprocation in the bosses and therevolution of one sleevepwill cause the other to revolve in a likemannenfl` y The one sleeve may have a hand wheel 14 for easy operationand'by means of the structure described a uniform plany forthe positionof the pressure board is assured at all times. i Y

The screw posts are rigidly'secured tothe board )supporting plates 15,vwhich are formed with upturned sides k16, ,as shown. The pressure boardproper is'fo'rmed of a central section larsecured'fast tothe lsupportingplates and two sidev4 sections 16a hinged to the central section.

The hinges 17, which accomplish 4this structure,v are equipped withsprings yadaptcd to close them and bring the side pieces to the positionshown in Figure 2, such that the main portion of theboardis lower than.

the two side pieces. Y yk. j

Ving bolts 18 are set in the turned-up ysides of the supporting plates,which `bolts bear on the hinged portions of; the` vside board, so that avariety of positions can be obtained illustrated .by Figures 2, 3, andl4,

whereby theglower surface of the pressurev board may be in a single planas in Figure 3y or a semi-convex form asin Figure 2 or a semi-concaveform as shown inFlgure 4. j

Set in the front and rear of the machine are shafts `19 and 20, whichcarry rolls 21 and 22, over which passes a conveyor belt 23. The spaceintermediate the 17W() conveyors may be taken up by any suitable`kneading board 24 (see my patent above referred to) `which presents tothe conveyor a corrugated supporting surface. Thus when rolls of doughare'engaged by the conveyor and caused'to travel through the machine,they will be'pressed down against the conveyor by the pressure board andwill re-v ceive the kneading action impartedfbyythe kneading boardandat'tlie same time will be given the proper taper'at the ends or towardthe middle ythat may be found de-l sirable.-

Theshaft 19 is the driving shaft for the conveyor device .and has asprocket thereon to drive a chain 25, which engages over a sprocket onthe shaft 20. This chain is i tensioned by an adjustable idler sprocket26.

The shaft 19 has on thel inside of .the

frame a gear 27 fast thereon, and on the outside of the frame is hung acasing 28., which 'journals .a wide gear 29. The gear 29 may be swung bythe fram'e about the aXis of the gearmQ', so that it will drive theshaft 19 from a variety of positions. A wing bolt l 30, heldin alug onlthe casing,'engages the side frame of the extensionunit, and by adi .ljustment Lof thek bolt, the position `of the casing and hence of thewide gear 29 may be readily adjusted.

In'the machinerof my patent and moreV particularly of my application forpatent,

- the' main lor kneading frame parts 3 1 are provided with conveyordrivingl means, ter- A minating in ay sprocket. 32, adjustable toabovedescribed, va variety of adjustments getheifvvith its ,shaft 133 insliding journal boXesf34. Y

By means of my planetary gearv device can becompensated for'when theextension y f1 l 1 unit 1s secured to the main lmeadmg frame lparts bythe raising vor lowering of this wide n gear,

' ing the es fa secu-ring 'device vfor my separable unit, I provide abracket l35 at the rear of,` the unit for the journaling of a rockshafty 36. At the front of the machine a cross bar 37 is mounted bymeans .of'bolts 3S engagframey standards and passing through slots r39in the cross bar. The shaft vpasses'through this cross bar and can movelengthwise with the cross bar 'when it is adjusted on its slottedmounting.

i 'i' The cross bar Ahas a central bloss 40 j soA a versely vpiercedywith slots 42,

through whichl the shaft passes, and also two projecting'arms `41, 41,which are transy The Shaft has a head 42a on its -end to which arepivoted two lockingl rods The arms 4 1 extend inside of main frame 31kto Which my device t0 be attached in such away as to snugly fit insidethe two y rearmost vertical standards thereof, and by Y rocking theshaft, the locking rods can be swung so as to slide in the slots 42.This will bring the ends of the rods 43 across the framey parts 31,thereby firmly clamping the two frames together without in any wayrequiring attachments on the frame of the molding machineproper.

The rolls of dough will pass from the machine proper to the extensionunit and there sary, and the unit can be quickly and firms-v ly attachedso as to be driven from thema-y chine proper. j

I havev not attempted to show` in great detail some of the parts of myextension y'be given such further treatment as neces# unit, and themechanic skilled in the artsy involved may readily devise other corres#pondmg structures for accomplishing the various features of my,invention without departing from the spirit thereof.
